| 摘 要： | 以广州某水厂源水为处理对象,研究在曝气生物滤池(BAF)+常规工艺中砂滤池的净水效果。研究表明,砂滤池出水CODMn、NH4+-N的平均值分别为1.19 mg/L和0.08 mg/L;相对于沉淀池出水,砂滤池对上述指标的平均去除率分别为27.41%和63.86%;砂滤池出水NO2--N几乎检测不出。砂滤池对分子量(10 K的溶解性有机物有较好的去除作用;砂滤池中DO下降了1.80 mg/L,分析表明在砂滤池中发生了完全硝化反应。

| Abstract: | Using Pearl River source water as raw water,the effect of water purification of sand filter in BAF and conventional process was investigated.The results show that the average values of CODMn and NH+4-N in sand filter effluent are 1.19 mg/L and 0.08 mg/L.Relative to the effluent of sedimentation tank,the average removal rates of CODMn and NH+4-N by sand filter are 27.41% and 63.86%,respectively,and NO-2-N almost can not be measured.The sand filter has a good removal effect on dissolved organic matter with mo... |
